So I got a deal on a used edelbrock performer 2101. My question is will it fit with my stock z28 hood and my q-jet and my air filter...and what exactly do I need to install this on? and is it worth the hassle...whats the power gain if any..

so far i got a full exhaust system..hooker 2055 headers, 3" straight pipes with a flowmaster at the end.

Rotate all hardware counterclockwise until loose.

Installation is the reverse of removal.

Yes

Tube of sealant, intake & valve cover gasket sets, handful of brass fittings from Home Depot for heater hoses and such, whatever you break taking it apart (there'll be PLENTY of that, vacuum fittings and the like), whatever "might as well"s you come across at the time like a new thermostat for example and various sensors, some coolant.

Sure; if your stock one is broken somehow (thermostat bolt broke off for example, or it's cracked)

On a stock LG4, basically zero; the intake isn't the bottleneck.

Good thing about it is, it has a CARB EO #. If you install it correctly, you can still get your car through inspection. One less thing you have to UNdo 2 years from now (like you'll be doing to your serious exhuast mistake). Good idea not to accumulate too many more such things, so you don't end up with an expensive lawn ornament.

great thanks this come sin handy...how long does it usually take to do this project kus this is my daily driver and I cant have it down for too long.....

and here are some pics of the manifold do I need an adapter to fit my stock q-jet on it, and what are the 4 bolts sticking out of it for ?and on the back I noticed this "thing" IDK what its for or if I even need it...?

The 4 studs is where you lower the car onto. You have 2 carb bolt patterns to choose from-- Square bore & Spread bore.
The thing with all the nipples is for vacuum line attachments.

i noticed that the nipple thing i can twist it off can i just block it off somehow...and between Square bore & Spread bore what you think is better?

iTrader: (13)

It unscrews but you will need a pipe plug to seal the hole if you take it out

You don't get a choice; your Q-Jet is spreadbore

You can block it off with a standard plumbing hardware you can get at Home Depot or Lowes. But you will probably need that port (not necessarily all of them) to connect to your brake vacuum.

Your stock carb, which you should re-use instead of that Holley, will require the rear 2 of those studs; but uses regular bolts in the front.

That particular PErformer isn't the one that will pass CA inspection. Doesn't have the EGR provision. Instant fail. Just one more thing you'll have to un- and re-do in a little under 2 years. Don't throw away, lose, or damage ANYTHING you take off. Take LOTS of pics so you don't have quite so much of a struggle getting it back like it's supposed to be.

Note that if you put that Holley on there, it will cover up that port where that nipple thing now is, and render it altogether unuseable; and it will require a VERY low-profile pipe plug to plug it without interfering with the carb. In fact, seems like the last time I put together that combo, I had to MAKE a plug that would work.

ohhh ok i see thank you guys and another question....those studs....cant I just remove them/twist em off??

85FBTranam

iTrader: (3)

Yes, double nut the stud and turn the bottom nut to twist them out. Won't hurt to give it a shot of some penetrating oil prior to make sure it isn't seized.

so i put on my spare q-jet i had laying around and it fit onto the rear two studs but as for the front ones will the stock bolts fir into it?

85FBTranam

iTrader: (3)

Use the studs you have.

sofakingdom

iTrader: (1)

Yup, your stock bolts will work fine.

i see you are in Cali.. this intake doesn't have an egr provision, so you will never, ever be able to pass an emissions test with this intake on it.. just keep that in mind..

having said that, you might gain a little bot of power and maybe even a little bit of fuel economy, but honestly the stock aluminum intakes they were putting on these cars in the 80's aren't really a bottleneck in the system.

well im not too woried about smog right now just becuase i have some ppl that can pass my car already..

calgutie

iTrader: (3)

alright you guys so what can I use /buy to plug up this whole??after i install the manifold?

sofakingdom

iTrader: (1)

If memory serves, I bought a ¼" brass pipe plug at like HD or something, cut the "head" off of it, cut a screwdriver slot in it, and Teflon-taped it to death.

calgutie

iTrader: (3)

hmm good idea ima look into that but originally what is that fitting thats on there can I somehow use that fitting and plug up the little holes on th efitting?

sofakingdom

iTrader: (1)

Orignally, that fitting serves the vacuum systems of the car, as distinct from the engine.... HVAC, cruise control, etc.

Sure, you can plug just about anything.

jaja got you well ill prov do that then if i cant find a nice fitting for it..thanks!

Alright you guys ever since I installed this think on it has been bad bad for more my car...I wanna say its leaking somewhere kus my car ever since I installed it has not been the same I am seriously tempted to install my OEM one back on....But the reason is that since then my car has been lagging and has gotten poor throttle response.....also when I hit the gas the rpms go up but the car doesnt really even move! Im just getting real aggravated with my car..

ChrisC

Where is your timing at? Weren't you having a timing related issue right after the swap?

calgutie

iTrader: (3)

I took ti to the mechanic but I believe its sucking in air form the manifold..

ChrisC

So you're saying you think you have a vacuum leak? Check all ports and vacuum lines. Grab a timing light and check your timing too while you're at it. I remember a post to which you said your vacuum advanced canister was not hooked up or something. This has been taken care of, yes?

So I finally took my car to the mechanic..aparently it had nothing to do with the manifold...Suprisingly it was a bad/faulty distributor...He ended up replacing a faulty control module inside the dizzy...but wow...it was incredible how much of a huge difference it made..It literally made my car launch!
